Wow - Hermes, Donna thanks you!  This painting was a long time in the making.  I liked the poster for Reservoir Dogs - high contrast,six guys in suits walking barren background.  So I tried to mimic it but using dogs.  I concentrated on getting their postures and grouping the same - but as it turns out dogs have a different anatomy than humans so it took a long time to approximate it.  Then it just wasn't working with hi-contrast no background , - so I cycled thru many variations and it sat for a month until I landed on this.
